  • Extruder cut-off knife assembly having remote adjustment mechanism
    Patent number: 8056458
    Abstract: A knife assembly (10) particularly adapted for coupling with an extruder barrel (26) is provided having a knife shaft (16) supporting a knife unit (14), with the knife shaft (16) axially rotatable and axially shiftable through fore and aft limits. The assembly (10) may be adjusted during operation without interrupting the axially rotation of shaft (16), using adjustment mechanism (24) located in a safely remote position from knife unit (14). The preferred assembly (10) includes axial shift limiting structure (114, 116, 124) serving to limit the extent of fore and aft axial movement of shaft (16). The mechanism (24) allows fine adjustment of the position of knife unit (14) relative to the extruder barrel (26), and also permits monitoring of the wear of knife unit (14).
